Toluene

IUPAC Name: Methylbenzene

MCL: 1 ppm

Source: Occurs naturally in crude oil. Used as a fuel additive, solvent, chemical intermediate, and explosive. Used in the production of rubber, paints, and many other household items.

Summary: Toluene is comprised of a benzene ring with a single methyl group attached. It is naturally occurring in crude oil and is a byproduct of gasoline and fuel production. It has many applications as an organic intermediate, solvent, fuel additive, explosive, adhesive, and is used in the production of rubber and paints. It is soluble in water up to 526 mg/L and has a density of 0.8623 g/mL at 20 C. Toluene is classified by the EPA as a Hazardous Air Pollutant (HAPs). Koc values ranging from 37 – 178 indicate moderate to high mobility within soil. Biodegradation and volatilization from soil and water are expected to be major methods of natural removal.
